    Little tip for the reinitialisation procedure, do not go to stop completely.
    You'll find reinit. procedure in french with pictures.
    Hi you saved my life (just the vacuum cleaner ). I would like to mention that the pictures are little confusing because the off position on picture looks exactly the same as the off position but it shouldn't be the same. There is little distance between those so after the resetting it, I had to put the regulator to the minimum position but not to the off position otherwise the vacuum cleaner never stops (the built-in plastic regulator couldn't go bellow).

    So the complete guide according to the French manual is:

    1. vacuum cleaner is off. Set the reset (reinitialisation) position on the speed regulator (do it by some tool because you cannot put the regulator to this position by the built-in plastic trigger). The reset position is in the top left corner (beginning of the clockwise circle)
    2. Turn on the vacuum cleaner for few seconds (3s or so) and do NOT move by the regulator. In my case the vacuum cleaner started and stopped intermittently. Now turn it off.
    3. Set the minimum position on the regulator. Now you can (should) do it by the built-in plastic regulator thing. Like I mentioned, it's not the absolute start of the regulator (the off position) but little bit more in clockwise. The minimum position is approximately the bottom right corner.
    4. Start the vacuum cleaner. Wait at least 3 seconds to let the electric board remember the minimum position and after these 3 seconds you can normally regulate to the max position (the end of the clockwise circle), then back to minimum position or even to turn it off when you move it less then the minimum.

    Hopefully, it will help to somebody else, like it helped me

    BTW: I did it on Electrolux Super Cyclone ZSC 69FD2. I didn't know how to fix the board so I bought a new one in some eshop.

    Hi,

    Has anybody else tested this?

    Can you describe the method to recalibrate again in your own words?

    I'm trying to follow the instructions, but It seems I am unable to calibrate the max speed to correspond to the correct max turning angle of the speed knob.

    Turn off and start on with minimum speed works, but turning the pot towards max speed only gets me some perhaps 50% of available speed. I need to turn the pot manually to get to 100%

    I am probably doing something wrong but after spending hours reading the french and Hagis2k guide I am stuck

    please somebody explain the procedure in their own words.

    Move your vacuum cleaner in a forward and backward movement slowly.

    Nah, all you gotta do is rip that Confuser out and put on of these in its place.



    As a bonus you also get a 10v overclock setting for those high-pile carpets!

    Very interesting. A friend reported me that he has a Electrolux/AEG vacuum cleaner that is showing this symptom (speed rises and falls by itself).

    But even more interesting is that calibration method that babas48 reports. I've recalled my brief experience with cooking robot Thermomix TM21:

    https://www.badcaps.net/forum/showthread.php?t=58675

    I realized that some sort of calibration of Speed and Temperature potentiometers was stored in a EEPROM. And the potentiometers were exactly of the same type than this vacuum cleaner. Perhaps that calibration is done in the same way that is explained in that french PDF.

    Is robot vacuum good enough that you don't ever need to manually vacuum? Please describe your floor situation (hard wood, carpet, etc), as well.

    Even so the new crazysales robot vacuum cleaner are meant to concentrate on different surfaces, it is actually still easy for the drive wheel for being stuck. Turn the unit backwards and inspect the wheels if you see the unit trying to move but not being able to. Try to get dirt, hair and other material which can find yourself in trouble concerning the wheels and the body. Clean this out and allow the Roomba go. This vacuum cleaner repair must be able to have your little guy running again.

    It starts then stops immediately, or just spins in place. It can be suggested that a person should clean the robot’s cliffbrushes and sensor, and brush bearings during these moments. Use compressed air, especially throughout the wheels and beneath the bumper, or tap the bumper in your hand. Another suggestion is to give the vacuum a firm push on top, directly above where the center wheel is situated, if this does not solve the problem. The challenge can be which the center wheel at the front of a unit is simply not in the proper recessed position because the wheel is adaptable. This Roomba repair method worked for several.

    Re: Vacuum Cleaner Speed Controller issues...

    So a final update everything now works and if someone ever would run it to the same problems with similar devices:

    The circuitboard has this partnumber: 2193995111
    the regulator ic: MC9S08QD4C
    Triac: BTB16-600

    And to avoid problems before you do like me, here is a small tip:

    Take a pen and draw a line where off and max speed corresponds to the potentiometer angle and please do not bring it outside those boundaries when you test make sure it is in "off" state...

    Otherwise a time consuming re-calibration is needed and this drove me mad, imagine the potentiometer in midpoint is "90 degrees" then -135 is the lowest and then you shall keep it there then plug the machine in.

    It will start and sound like a tornado, do not worry about that then turn the potentiometer to max then back to min now unplug the the vacuum cleaner.

    Now we have the last step to set the off state in the right position on the pot and on state too (must start with potentiometer at max +135 degrees from midpoint) then try to look at the axle where like full speed is on the pot and where off should be then set it where like full speed should be and a few degrees extra counter clock-wise and plut it in now it should be in max speed now take a small insulated screwdriver and turn the pot clock-wise until it turns off with a bit of luck that will match the angle of the axle of the pot.

    Otherwise you need to repeat the reset and set again.

    Thank you RJ!!! i was looking at that capacitor C2 before and its was that MKT capacitor that was bad now it responds up to full speed but it still needs a calibration and now it makes sense

    Re: Vacuum Cleaner Speed Controller issues...

    Yes i was looking at that one for a while (C2) it says 474/250V 470nF i guess but my component tester says 154nF ESR=8 or so i assume its bad the other (C1) 334 330nF measures 261.nF ESR=3.2 so thats true.

    And no im not that good with polish even if it is close to me haha

    Saw that polish site too seems like MQD4C is a microcontroller?

    Try to source some capacitors then

    The larger of the Yellow capacitors looks like it may be bulged a bit at the bottom (near D1), I would check it, sometimes they go open and don't look bad.
    And it is off the center of the pot through R1
    I found this also, Hows your Polish?

    Re: Vacuum Cleaner Speed Controller issues...

    So tried to resolder some joints, and it still acts up like it is power cycling i wonder if the controller ic is faulty?

    Tried to upload some real high resolution macro photos of the pcb but the size was way to big so here they are:

    http://i.imgur.com/vxJoQlY.jpg
    http://i.imgur.com/wuDjADc.jpg
    http://i.imgur.com/jjwr4U3.jpg

    I tried a few times more to turn the pot for full dc voltage and plug it in then to put the pot to gnd and then plug it what confuses me is when i have it in the lowest then the motor is running in full speed without dropping any speed
    can the micro controller be faulty anyway shall call the service center and double check the "calibration" procedure.

    go resolder some joints.

    also, the zener diode on top looks cracked - is it? or is it the camera angle?

    Electrolux EUO9GREEN Vacuum Cleaner doesn't start
    by Henke
    I have a vacuum cleaner that won't start. I have desoldered 2 capacitors with low value. But i don't know if they can cause that kind of problem. Someone here with any thoughts and inputs?

    I marked the capacitors on the pcb picture with red and blue dots. The big one marked with 334 K measures 216 nF and the other one marked 224 K measures 109 nF.

    Electrolux ERG22 vacuum cleaner pcb fault
    by Crystaleyes
    So, I have this Electrolux vacuum which had the batteries revently replaced and now it won't work.

    The voltage from the batteries is arriving to the board without problem (+/- 12v) @ CN4 & CN6.
    The motor works fine when voltage is applied to FM+1 & FM-1. The switching on and off is made in the negative line between CN6 and FM-1, and all components have been tested as fine apart from a FET.

    The problem appears to be that the PHD71NQ FET (Q18) isn't switching when the power button is pressed.

    I say this as when I started to connect my component...

    Replacing the WiFi module on a vacuum cleaner iROBOT i7
    by AlexVG
    Hi,
    I have had an iROBOT i7 with a camera error (error 68) version REV M, year 2018.

    I bought a liquid damaged Mainboard with WiFi module, from the same vacuum cleaner, but a different year and a different version (REV G).
    (This board does not respond, only the LEDs light up in a circle.
    The liquid damage is catastrophic and restoration is impractical).
    (I bought this board to get the WiFi module and camera).

    The boards are completely different in the installation of elements, even the connector for the WiFi module is different.

    Arduino Nano Controller with a 15 watt Laser hook up issues
    by sam_sam_sam
    This project that I am working on the Engraving Machine has been a challenge to make everything to work together

    The information on the internet is hit and miss for the most part
    It is a good thing that I know how and what it takes to hook up most micro controllers yes each model is a little bit different but for the most part they are the same

    The BIGGEST problem has been the markings on these Arduino Nano Controller boards not all are the same some board are marked better than others

    You see how I have to hook up the laser and Nano Controller...
